Abstract (en)
[origin: ES8302548A1] Disclosed is a pressure sensitive recording unit which comprises a single base web sheet and a methine-type dyestuff and an organic oxidizing compound both supported on the single base web sheet, or a combination of first and second base web sheets and the methine-type dyestuff and organic oxidizing compound supported individually on the first and second base web sheets. Such a recording unit includes for example a pressure sensitive recording unit formed in combination of (a) a back-coated topsheet (CB-sheet) making use of microscopic capsules containing a solution obtained by dissolving a methine-type dyestuff in a solvent having a high boiling point and (b) a front-coated undersheet (CF-sheet) carrying an organic oxidizing compound coated thereon. Also disclosed is a pressure sensitive recording unit which includes a base web sheet carrying thereon such a methine-type dyestuff together with a metal ion sequestering agent and/or alkanol amine.
